Members of Peploglyptus can be distinguished from other Onthophilinae by characters of the pronotum and elytral structure. The genus is characterized by a compact, convex body with shortened that expose one or two abdominal tergites. Specific diagnostic features require examination of male genitalia and detailed pronotal sculpturing patterns.
Distribution
of Peploglyptus have been recorded from North America (P. belfragei), South America (P. golbachi from Argentina), and Southeast Asia (P. mulu from Borneo). This disjunct distribution pattern suggests the may be more widespread but undersampled.

As with other Histeridae, in this likely function as or scavengers in decomposing organic matter, though specific ecological roles have not been documented.

Taxonomic history
The was established by John Lawrence LeConte in 1880 with P. belfragei as the type . Two additional species were added in 1981 and 2005 respectively, indicating continued recognition of the genus but limited recent taxonomic activity.
Collection rarity
The single iNaturalist observation and sparse literature references suggest Peploglyptus are either genuinely rare, cryptic in habits, or occur in infrequently sampled by entomologists.
